re: Cisco Pitches MPLS Alternative

Reading the Cisco whitepaper on EVN, it looks to me like old wine in new skins. What is it more than some simplified configuration commands for VLAN separated Multi-VRF? Ok, it's always good to simplify the configuration for the user.

Your assessment might be correct. Cisco described EVN to me as using familiar campus-network skills to configure logical networks.

There is a standard, E-VPN which has been written about by ACG

Tag switching, without the need for BGP so long as all end-nodes are in the same physical network (ie reachable to each others w/o going through public Internet)?


Isn't this what L2 MPLS-TP is supposed to do: Simple forwarding tag based L2 switching?


MPLS-TP is an open standard with systems available from number of competing vendors at competitive pricing, where as "EVN" is de-facto Cisco technology. Which way should a cost-sensitive enterprise go for?

Here's an evaluation that Cisco's EVN is not only not-new, but doesn't really count as a "technology":

That's from Ivan Pepelnjak's blog at IPspace.net, and he did dig into the technology quite a bit.

EVN is not proprietary as it works with other vendor kit at remote end of connection using standard VRF lite commands.
